본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 차폐구조를 도시한 개략적인 요부 단면도, 제2도는 본 발명의 차폐부재를 도시한 평면도, 제3도는 제2도의 A-A선 단면도.1 is a schematic cross-sectional view showing a main portion of the shielding structure of the present invention, FIG. 2 is a plan view showing the shielding member of the present invention, and FIG.

Claims (2)

모터에 의해 구동되는 구동축이 캐비티저벽을 관통하여 턴테이블과 연동하도록 이루어진 턴테이블 구동부에 있어서, 차폐부재(1)는형상으로 절곡한 정중앙에 관통구멍(2)을 형성하여 테두리를 상향돌출되게 절곡하고, 그 관통구멍(2) 을 중심으로 서로 대향되게 H높이를 갖는 다수의 상향돌출부(3)를 형성하여 전자파를 차폐함과 동시에 자연소멸되도록 이루어진 차폐부재(1)를 상기 캐비티저벽(4)의 바깥쪽 면에 용접되는 것을 특징으로 하는 턴테이블 구동부의 전자파 차폐구조.In the turntable driving unit, in which a drive shaft driven by a motor is interlocked with a turntable through a cavity wall, the shield member 1 Through holes 2 are formed at the centers bent in a shape to bend the edges upwardly, and a plurality of upwardly projecting portions 3 having H heights are formed to face each other about the through holes 2 to form electromagnetic waves. Electromagnetic shielding structure of the turntable driving unit, characterized in that the shielding member (1) made to be shielded and at the same time natural dissipation is welded to the outer surface of the cavity wall (4). 제1항에 있어서, 상기 상향돌불부(3)는 그 H높이가 0.6cm인 것을 특징으로 하는 턴테이블 구동부의 전자파 차폐구조.2. The electromagnetic shielding structure of a turntable driving unit according to claim 1, wherein the upwardly projecting portion (3) has a H height of 0.6 cm. ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
